Mr. Sean Laffey:

It is because we know that if we have capacity in a wastewater treatment plant for 1,500 homes and we give away capacity for 500 homes, we then have capacity left for 1,000 homes. If the local authority tells us it needs to build 2,500 homes in the next five years in that location, then we would be 4,000 population equivalent short, so we would have to invest.
